SWITCH-LAMP.

To all whom it may concern.-

Be it known that I, THEODORE B. OSBORNE, a citizen of the United States,and a resident of Plainfield, in the county of Union and State of NewJersey, have invented certain new and useful Improvements in SwitchLamps, of which the following is a specification.

.My invention relates especially to lamps or lanterns employed atrailway-switches, 8m, 10 and has for its object the provision of acheap, simple, durable, and effective device to prevent theextinguishing of the light by reason of sudden jars caused by thepassing of trains over the switch wherewith the lantern is used.

The invention consists, essentially, in a spring interposed between thesocket-plate fitting upon the switch-staff and the body of the lantern,suitable means being employed to permit the vertical movement of thebody, all of which will be hereinafter first fully described, and thenpointed out in the claim.

In the drawings, Figure 1 is a view in elevation of a switch or signallantern wherein my improvement is employed, the bottom part thereofbeing shown in section; and Fig. 2 is an enlarged view of a fragment ofthe base of the device, illustrating the method employed for securingthe parts together while permitting a vertical movement of the body ofthe 0 lantern upon the socket-plate.

Like letters of reference wherever they occur indicate correspondingparts in both the figures. V

A is the body of the lantern, provided with 5 a hollow base or skirt, B.Ois a socket-plate,

preferably made of cast metal, said plate havthrough which rivets or ingslots 0 therein,

projections D, secured to or formed upon the skirt or base, extend. E isa spring interposed between the lantern plate.

WVhen constructed and arranged in accordance with the foregoingdescription, and placed in position upon a switch-staff, it will at oncebe seen that while the socket-plate fits rigidly upon the staff thespring thereabove will prevent a sudden jar of the lamp, and sufficientplay in a vertical direction is given to the lantern-body to permit freeoperation of the spring. 5

I am acquainted with Letters Patent No. 55,255, issued to Dodge June 5,1866, for an improvement in car lamps, and with No. 319,094, issued toHuntington June 2, 1885, for an improvement in switch or signal lamps,and to the constructions therein shown and described make no claim; but,

Having now fully described my invention, what I claim as new therein,and desire to secure by Letters Patent, is-- The combination, with thesocket-plate 0, having the outer depending flange provided with slots 0therein, of the body A, having skirt or base B, provided withprojections D, and the spring ranged substantially as shown anddescribed.

Signed at New York, in the county of New York and State of New York,this 6th day of June, A. D. 1885.
